To all wlw/init may concern:

Be it known that l, FRANK W. GAULT, J r., a citizen of the United States, residing at Ulrolona, in the county of Jefferson and State of lientucliy, have invented a new and useful Gaswllurner, of which the following.,r is a specification.

rlhis invention relates to gas burners.

Gas, both artificial and natural is widely used, in industrial plants on account of its adaptability to conditions and its susceptibility to regulation.

l n object oi this invention is to provide a burner wherewith may be burned so as to produce a low flame of wide area, sirnulatingg' Jdie appearance and eitect of a bed ot Iglowing coke.

another object is to provide a burner, which when. used in connection with the air and gas mixer, described and claiined in Patent #1,286,582, granted to applicant Decernber 3, 1918, will produce conditions that have long' been sought in certain arts, such as candy making, wherein it is essential that the heat be evenly distributed over a wide area of the bottom oi a receptacle, such as a kettle. With the i'fores'oing1 and other objects in view, the invention consists o'l" the novel construction and arrangement ot parts illustrated in the accompanying' drawing, which toi-ins a part ot this specification, wherein is set forth an embodiment of the invention, but it is to be understood that such changes and iuodiications may be resorted to as come within Jche scope ol" the claims appended hereunto.

ln the drawing, wherein similar reiterence characters designate like parts in the several views, Figure 1, is a perspective view ot an embodiment of the invention: Fig. 2, a plan view: Fig. 3, a central longitudinal section: Fig. 4, a section on line 4.-4: of Fig'. 2: Fig. 5, a detached detail ,showing the method of adjusting the burner plate: Fig. 6, an elevation of the adjusting screw and Fig. 7, a View showing` a method oi using' the burner.

rl`he burner designated as an entirety by the reference numeral -10-, comprises a body -11- formed preferably as an integral casting; consisting; ci a bottom and vertical side walls, it is made massive to resist the action ot heat, and is cast in sand, in Vorder that the `surface may be rough. A ledge --12- extends around the inside, a spaced distance from the bottoni, a burner plate -13- disposed upon the ledge divides the interior into two portions, a lower or distribution chamber #-14- and an upper, or combustion chamber -15-. rlhe body is provided in its lower portion with a screw threaded aperture -1G which opens into the distribution chambe and is adapted for the reception oi2 a supply pipe 1T-1 The roughness of the surface of the body is such that the burner plate does not lie close on the ledge, nor do its edges lie close against the walls,consequently `,das will pass around the edge et the plate and being ignited will forni wh at l terni a lazy flame. il plurality et slits, W18, 19- arranged in two groups, entend inward iroin the opposite edges of the plate in alternate parallel relationship, to within spaced distance of the opposite edge. rllhe slits are very narrow and open into the space between the edge of the plate and the wall, and gras which passes through them is lighted by the lazy ila-ine. `When used in connection with my mixer, as previously 1nientioiurl, there is considerable pressure eX- erted on `the underside oi the burner plate, and means must be provided for holding' it in position. For so holding the plate and adjusting` it to and from the ledge, I have provided a screw' having a head -20- a neck --21 and a threaded body portion The plate is provided near each cor ner with a` :marginal recess -23, extended in from the edge thereof, which is adapted to receive the neck of a screw. To place the plate in the burner, the necks of the screws are placed. in the recess, the screws hanging pen dent therefrom, the plate is then lowered into the burner and the screws engaged in screw threaded holes Q4- in the ledge, the screws are then turned by means of a screw driver to draw the plate down to the desired position where it will be securely held, the head of the screws preventing,P it from being blown out by the air pressure and the shoulder holding it spaced from the ledge.

l have observed that with gas at a normal `pressure of about 5 ounces and with a low air pressure, a high flame is produced, but as the air pressure is increased the flame is reduced .until at a pressure of pounds or upward, a low kblue flame is formed which I term a blanket flame.

In Fig. 7, the burner is shown as supported by a stand -25-, beneathV a kettle -26-, the kettle being' upheld by a stand Having thus described my invention so that others skilled in the art ,pertaining thereto can ina-ke and use the same,

, I claim: Y

l. A burner comprisinga body having` vertical walls, Va ledge extending' inward from the sides of said walls a spaced distance from the botto-ni thereof, a burner plate having` ka plurality of slits extended inward from the edges thereof, said plate being supported yby said ledge, and means for introducing; gas into the space beloiyv the plate.

2. In a burner as characterized, a body comprising a bottoni and integral vertical :side walls, fa supporting ledge extending 'around the inner side of said wall a spaced distance above said bottoni, and a burner plate resting; on said ledge, dividing the interior into distribution and combustion chambers, the edges of said plate being a spaced distance from .the walls, the body having` an opening in the lower portion. thereof for the recept-ion of a feed pipe.

3. In a burner as characterized, a body comprising' a bottom and integral vertical side walls, a supporting ledge extending around the inner side of said walls a spaced distance above said bottoni, a burner plate resting on said ledge dividing' the interior into distribution and combustion chambers, said plate being' provided with a plu `ality of slits extended inward from opposite sides thereof in alternate parallel relationship, and adjusting screws mounted iny said ledge, each of said screws comprising a head, a neck and a body portion, the plate having marginal recesses for the reception of the necks of said screws.

4f. A burner comprising a body having vertical walls, a burner plate provided with a plurality of perforations supported within said body, a spaced dist-ance below the top (hereof, and a plurality of adjusting screws each comprising a body, a neck and a head, the plate having` marginal recesses for the reception of the necks of said screws.
